I have iMac intel OS Lion, very new mac user. Due to some reason I couldn't change anything on my desktop files and folder. I could not able to trash anything from my desktop only (I was able to trash other files (which are not on desktop). If I tired to trash,rename or moving any desktop items, system was asking for login and password, but it was not working. So I have been told to perform Reset Password thru Utilities/Terminal. So, as of right now Reset Home Folder Permissions and ACLs is running since 24 hours with no luck. I kept some thousand of medical records files with other 5000 epub titles in on folder on desktop (may be stupid). but please advice me to regain atleast old state. Your help will be highly appreciated.
